Siri: Tweet and Post to Facebook in iOS 6 from Lock Screen

iOS 6 introduces a cool feature that lets you tweet and post to Facebook from the Lock Screen using Siri. While this adds a layer of convenience, it also introduces a privacy and security problem. You don’t want someone passing by to grab your iDevice and send out random messages.

First I’ll show you how the new Siri feature works in iOS, then how to disable the feature in Passcode Lock Settings.

Tweet and Post to Facebook from iOS 6 Lock Screen

While at the Lock Screen on your iOS 6 device, hold down the Home button to launch Siri.

Then tell Siri you want to tweet a message or post to Facebook.

Speak the message you want to send, and Siri will send it off.

Disable Siri with Passcode Lock Setting

To disable Siri’s ability to send posts from the Lock Screen, you’ll first need to enable a Lock Screen Passcode. Go to Settings >> General >> Turn Passcode On.
